TYPE-WRITER.

Application filed ()ctober 17, 1918.

To all whom it may concern:

Be it known that I, Josnrn Boncnin, a citizen of the United States,residing at Seattle, in the county of King and State of lVashington,have invented certain new and useful Improvements in Type-Writers, ofwhich the following is a specification.

This invention relates to improvement-s in typewriters and has for itsprincipal object to provide an improved and novel device forautomatically returning the carto normal position.

The primary object of the invention is to provide simple and economicalelectrical means which when the carriage reaches the end of a line acircuit will be closed, and the carriage will be automatically returnedto normal position.

In the accompanying drawing the figure represents diagrammatically aportion of a typewriter, and a carriage with the improved mechanismapplied thereto. y

Referring more particularly to the draw ings, numeral 1 indicates theframe work of a typewriter upon which is mounted a carriage 2 whichcarries a platen roll 3. In

order to bring the carriage 2, back to its normal-positi on, I provide asolenoid 18, and cooperating armature 19 mounted upon a pivoted lever20. Lever 20 extends vertically beyond the solenoid and is connected bya bar 21 to the vertical arnnof a bell crank lever 22, which is pivotedto the frame of the machine 1. A cord 23 is connected to the horizontalarm of the bell crank lever '22, said cord being trailed over. a pulley2%,.and at its end it is connected to the carriage 2. The opposite endof the carriage 2 is provided with a contact 25, which is adapted toengage another contact 26, located on the frame 1, at the end of thetravel of the carriage. The engagement of the contacts 25 and 26, closesa circuit 27 in which is a battery 28, thecircuit leading to thesolenoid 18.

When the solenoid is energized. it attracts Specification of LettersPatent.

the armature 19, thus drawing the levers 20, and 22, toward it, therebydrawing upon the cord 23, sufiicient to pull the carriage back to normalposition. It will be understood that the mechanism for returning thecarriage operates automatically, and is therefore independent of theoperation of the In typewriter mechanism, a frame, a carriage to slidethereon, a pulley connected with one end of the frame, a bell cranklever having a long arm and a short arm and p ivotally connected withthe frame, said long arm extending toward the pulley and arrangedbeneath it for vertical movement toward and away from the same, aflexible element secured to the free end of the long arm and passedabout the pulley and attached to the carriage, a vertically swinginglever arranged near and beneath the opposite end of the frame, means forpivotally, supporting the lower end of the vertically swingino; lever,an electro-magnet arranged upon one side of the lever near its pivotpoint with the lever extending beyond the electromagnet for asubstantial dis tance; a rod pivotally connected with the free end ofthe vertically swinging lever and withthe free end of the short arm,said eleetro-magnet located in an electric circuit and means to closethe circuit when the carriage has moved to the end of its travel in'onedirection.

In testimony whereof I afiix my signature.
